HISTORICAL ACCOUNT OF THE HERBARIUM. 
47 
The species and varieties already entered in the catalogue are 
numbered from i to 729 inclusive, and these are represented by 
over two thousand specimens. 
The work to be done in the herbarium includes entering the 
names of over one thousand species and varieties in the catalogue, 
and the mounting and labelling of over three thousand specimens. 
In addition to this work, information is desired in connection 
with 
(a) The donors and collectors of the specimens. 
(b) Changes that have taken place in such Yorkshire localities 
as Terrington Carr, Staveley Carrs, Strensall Common, &c. 
(c) Evidence relating to the extinction or introduction of plants 
in Yorkshire from 1760-1906. 
The Donors and Collectors of specimens. 
Your honorary curator, in submitting the following prefatory 
notes, respectfully asks those members who are interested in any 
of the above subjects to help the society with their knowledge and 
advice, which will be duly acknowledged. 
The pursuit of botany offers an immense field for work, and the 
student can spend a life-time in investigating any of the divisions 
of the Vegetable Kingdom. 
Some members of our society have commenced by studying the 
plants of Yorkshire, and then gone forth to foreign lands in search 
of knowledge ; whilst others have confined their observations to 
England, and have left valuable collections of plants to this 
society. 
As they have been workers in the field, so let 11s be earnest in 
our endeavour to preserve their work, and be fellow-w 7 orkers in 
carrying out the object for which this society w r as formed. For 
there is work for all: Nature knows no rest, night and day the 
pages of her wonderful book are offered to those who are willing 
to learn. It is refreshing to be for awhile in the midst of Natural 
History and Antiquarian objects of interest, that serve to illustrate 
the history of the past and life of the present. 
The least that can be done to keep green the memory of such 
honoured names and pioneers of Yorkshire botany as Dalton, 
Hailstone, Backhouse, Hincks, Middleton, Munby, Moore, and 
Spruce, is to treat with care the flowers they loved so well.
